A ball is affixed to the top of flexible supports, allowing the ball to move in an arc once it is struck. A timing light is provided for illuminating a lens to indicate the proper time for the user to strike the ball. Various sensors are included for determining whether the ball was correctly struck. A number of parameters relating to the manner in which the ball was struck are sensed and recorded.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is directed to the field of sport training devices.

2. Description of the Related Art

Many individuals participate in sports both as a pastime, as well as a hobby. As can be appreciated, it is important when participating in a particular sport to develop a proper technique in playing the sport to increase an individual's level of play, as well as to prevent injuries.

Therefore, many techniques have been developed for assisting an individual with improving their technique. With respect to a sport involving hitting a ball, a number of different devices have been developed to enable an individual to better improve his or her performance. For example, and with respect to a racquet sports such as tennis, racquetball or squash, U.S. Pat. No. 5,003,558 to An teaches the use of a training device provided with a uni-directional flexible spinner. This device includes a ball mounted on a flexible support column. In use, the individual would strike the ball at a top most position, forcing the ball away from the individual. Once the ball provided on the support column reaches a first position away from the top most position, it would return from this position to a position closer to the individual. At this point, the ball would then oscillate back and forth until it again reaches the top most position. During the use of this training device, the individual would endeavor to strike the ball when it returns to the top most position. This type of device would allow an individual to practice his or her technique in properly striking the ball without the necessity of including a partner in the training technique. However, the device described in the An patent would not afford the individual with any indication that the ball was properly struck.

SUMMARY OF THE INVENTION

It is, therefore, an object of the present invention to provide a sport training device, such as a reciprocating ball sports trainer, to assist an individual practice hitting a ball with an implement, such as, but not limited to a tennis racket.

It is a further object of the present invention to provide a sport training device including an illumination device for determining the proper time for the individual to strike the ball and to collect practice information for later evaluation.

It is yet another object of the present invention to provide a sport training device with various sensors for determining whether the ball has been properly struck.

The present invention addresses the deficiencies of the prior art by providing a sport training device, such as a reciprocating ball sports trainer, allowing an individual to practice hitting a ball with an implement such as a racket or bat, as well as providing an immediate indication whether the ball has been properly struck. In addition, the individual is provided with a record of his or her performance which can be reviewed by themselves or a professional. This is accomplished by providing a reciprocating ball sports trainer including a ball affixed to a flexible support assembly, and allowing the support and the ball which is attached thereto to reciprocate when the ball has been struck. The location of the ball is constantly monitored each time the ball is struck. The amount of force applied to the ball when struck by an individual can also be determined. Information relating to the manner in which the ball has been struck is recorded and is analyzed in real time or after a practice session has been completed. The reciprocating ball sports trainer is fitted with wheels, skid pads or traction pads, allowing the sport training device to be steered, freewheeled, braked or slid after each impact with the ball. The direction and amount of travel of the sport training device can be controlled by varying the degrees of the wheels and/or the amount of resistance to movement.

A ball motor/generator is located in proximity to the ball. The ball motor/generator detects the rotation of the ball. This is accomplished by monitoring pulses created by the rotation of the ball. Therefore, the speed and direction of the ball can be calculated. In addition, the motor/generator can assist the individual to spin the ball and create the effect of top or back spin. The amount of spin produced by hitting the ball is augmented or reduced through the use of a spin retarder which is placed in proximity with the motor/generator.

The present reciprocating ball sports trainer also includes a timing light providing a light which illuminates a lens when the ball has reached the exact point that it should be hit by the user, for example, the top dead center point. The timing light uses a light source located in the bottom of the flexible support assembly such as a hollow spring that holds the ball. When the ball reaches the top of its arc, the timing light illuminates the lens or opaque cover provided at the top of the flexible support assembly resulting from the light passing unimpeded from the bottom of the flexible support assembly to the top of the flexible support assembly. This indicates that the ball has reached the top of the arc at the top dead center position. As the flexible support assembly bends past the top dead center, the light is no longer illuminating the lens or cover due to the bending of the flexible support assembly, thereby indicating to the individual that it would not be the proper time to strike the ball. This action is repeated each time the ball passes the top dead center point.

A timing sensor is provided producing a signal when the individual strikes the ball. The timing sensor includes an illumination device provided in the base of the flexible support assembly and a reflector provided at the top of the flexible support assembly in a direct line with the illumination device. Since the timing sensor is in direct line with the reflector, light impinges on the reflector only when the flexible support assembly is at the top dead center position. Light impinging upon the reflector is reflected back to the bottom of the flexible support assembly to be received by a photo detector. Therefore, if the ball is struck when the flexible support assembly is at the top dead center position, a signal is produced indicating that the ball was struck at the proper time. However, if the ball is struck when the flexible support assembly is not at the top dead center position, a signal is produced indicating that the ball was not struck correctly or at the proper time. A controller provided with a microprocessor and memory is used to calculate and store the number of “good hits” and the number of “bad hits”. Additionally, an audio signal could be produced when a “good hit” has been struck.

Information produced by the timing light and timing sensor, as well as sensed by the ball motor/generator is transmitted to the microprocessor within the base of the reciprocating ball sports trainer. The microprocessor includes a memory in which information generated by the reciprocating ball sports trainer is stored. This information, along with the output from the ball motor/generator is utilized to analyze the manner in which the user has struck the ball. The microprocessor would provide real time, or post time information produced by the device. In addition, the device can display information relating to future goals, times, percentages, averages, correct and incorrect hits, impact velocity, as well as position data and any other information appropriate to the technique being developed by the individual. The reciprocating ball sports trainer can be internally or externally powered, recharged via external sources or internal such as kinetic energy generators, solar devices or other means. Real time monitoring by the user would also allow for real-time feedback, as well as possible interfacing to other interactive or storage devices such as a computer or some other user in real time with a like device such as a Wii. Information relating to the manner in which the individual is performing can be provided in a display included at the base of the sport training device.

Other objects and advantages of the present invention will become apparent from the following detailed description when viewed in conjunction with the accompanying drawings, which set forth certain embodiments of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The detailed embodiment of the present invention is disclosed herein. It should be understood, however, that the disclosed embodiment is merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limiting, but merely as a basis for teaching one skilled in the art how to make and/or use the invention.

As previously explained, the purpose of the sport training device 10 is to allow an individual to practice hitting a ball 12 with any sort of implement, such as, but not limited to a tennis racquet, racquetball racquet, squash racquet and baseball bat. However, for purposes of simplicity, the present invention will be explained with respect to training an individual to properly strike a tennis ball with a tennis racket.

The reciprocating ball sports trainer 10 includes a ball 12 attached to a flexible support assembly 11 including a first vertical spring 18 and a second vertical spring 20 parallel to the first vertical spring 18, as well as a first housing 22 and a second housing 24. A ball 12 is attached to a U-shaped ball mount 14 with a portion of the ball 12 extending beyond the end of the ball mount 14 in such a manner to allow the ball 12 to rotate when struck by the tennis racket. One or more bolts 50 secure a back plate 49 to the ball mount 14 as shown in FIG. 4, with the top of the spring 18, 20 provided between the back plate 49 and the ball mount 14. As shown in FIGS. 1 and 2, a portion of the springs 18, 20 will extend to, but not into the separate housings 22, 24 respectively. However, as shown in FIG. 5, the housings 22, 24 can be eliminated. Both the vertical springs 18, 20 as well as the housings 22, 24 are hollow. The length of each housing 22, 24 is not crucial to the operation of the present invention and could extend very close to the top ball mount 14, or be provided a relatively large distance from the ball mount 14. Housing 22 includes a top outer tube portion 23 and a bottom inner tube portion 27. Housing 24 includes a top outer tube portion 25 and a bottom inner tube portion 29. A tightening ring 19 would secure the bottom of spring 18 to the top of the top outer tube portion 23 and a tightening ring 21 would secure the bottom of spring 20 to the top of top outer tube portion 25. Since individuals utilizing the reciprocating ball sports trainer 10 will of different heights, it is important that the height of the ball 12 with respect to the individual could be adjusted so as to be the proper height for each individual. Therefore, the exterior of the housing 22 is provided with a first height adjustor 46 and the exterior of the housing 24 is provided with a second height adjustor 48. Movement of each of the height adjustors 46, 48 changes the height of each housing 22, 24 as well as the height of each of the springs 18, 20. Therefore, the height of the ball 12 and the ball mount 14 with respect to the individual user is adjustable to accommodate children as well as adults of varying heights. Both of the housings 22, 24 are attached to a base assembly 74 through the use of a spring clamp 72 and bolt 70 as shown in FIG. 7.

The height of the housing 22 is changed by telescoping the bottom inner tube portion 27 into or out of the top outer tube portion 23. The height adjustor 46 is a ring which threads down over the bottom inner tube portion 27. As the height adjustor 46 threads down, it tightens the top outer tube portion 23 around the bottom inner tube portion 27. Similarly, the height of housing 24 is changed by telescoping the bottom inner tube portion 29 into or out of the top outer tube portion 25. The height adjustor 48 is a ring which threads down over the bottom inner tube portion 29. As the height adjustor 48 threads down, it tightens the top outer tube portion 25 around the bottom inner tube portion 29. As can be appreciated, the height of both of the housings 22, 24 should be equal to one another during use of the reciprocating ball sports trainer 10.

The first base assembly 74 is mounted upon two longitudinal members or skids 26 which diverge from the base assembly point 74 as illustrated in FIGS. 1-3. The base arms 26 act as a base to support the springs 18, 20, the housings 22, 24 and the electronics and illumination devices used to operate the reciprocating ball sports trainer 10. Each of the base arms 26 is provided with separate handles 28, 30 for ease of moving the reciprocating ball sports trainer 10 from one location to another location. FIG. 1 includes a wheel or roller 38 attached to the ends of each of the base legs 26 at the end opposite the handles 28, 30. A butterfly nut 68 (or similar device) as shown in FIG. 3 attaches the wheel or roller 38 to the connection point of the base legs. As illustrated in FIG. 5, a skid pad 56 or similar device could be substituted for rear wheel or roller 38. As can be appreciated, striking the ball 12 with the roller 38 is attached to the base legs 26 causes the reciprocating ball sports trainer 10 to move more easily than having the skid pad 56 attached to the skids 26.

As shown in FIG. 7, two load cells 32, 34 are provided immediately above the base assembly 74 for use in determining whether a ball 12 is properly struck by the individual. One load cell 32 measures the lateral motion of the springs 18, 20 and the second load cell 34 measures any reciprocating movement of the springs 18, when the ball 12 is struck. The purpose of these load cells and the manner in which they are utilized will be subsequently discussed.

FIGS. 3, 6 and 7 illustrate the reciprocating ball sports trainer 10 of the present invention with various components removed from an operational reciprocating ball sports trainer 10 for ease of illustration. As shown in FIGS. 1 and 4, the ball 12 is provided between the two arms 13, 15 of the ball mount 14. A ball motor/generator 42 is provided in the interior of the ball 12. The ball motor/generator 42 is designed to allow the direction of the rotation as well as the speed of rotation of the ball 12 to be detected and measured. The ball motor/generator 42 includes an armature and rotor mounted within a small tube provided within the ball 12 itself. The two ends 42 a, 42 b of the ball motor/generator 42 secure the ball 12 to the ball mount 14 through the use of two end caps 16, allowing the ball 12 to rotate between the two arms 13, 15 of the ball mount 14.

Once the ball 12 is struck by the tennis racket or other device, the ball 12 reciprocates about an arc as shown in FIGS. 8 and 9 through the reciprocating movement of springs 18, 20. However, the housings 22, 24 are fixed in place but would slightly flex in both a traverse and/or lateral direction based upon the manner in which the ball 12 has been struck. At this time, as will be explained, the rotation, direction, as well as speed of acceleration and deceleration of the ball 12 is detected. This information is transferred to microprocessor (not shown) provided in the base assembly 74 of the device. In operation, the rotor is affixed and the armature spins around the rotor of the ball motor/generator 42. The rotor is connected to the end cap 16 and two small wires transmit the electrical signal sent by the ball motor/generator 42 to the rear 17 of the ball mount 14 to which the two small wires are connected to small electrical contacts. These electrical contacts allow the electrical connection to be transferred from the ball motor generator down through the flexible support assembly 11 to the microprocessor provided in the first base assembly 74. Two additional electrical contacts are connected directly to the microprocessor allowing the processing of the motor/generator signals to take place. Additionally, as will subsequently explained, signals from the ball motor/generator 42 as well as signals received from a timing light and the load cells (or sensors) 32, 34 are also processed and stored within the microprocessor. As best shown in FIG. 7, the lateral load cell 32 is provided between the springs 18, 20 at a small distance above the base assembly 74. Similarly, the reciprocating load cell 34 is also provided between the base of the springs 18, 20 and immediately above the top of the base assembly 74.

The lateral load cell 32 and the reciprocating load cell 34 are designed to determine the positioning of the ball 12 by measuring the amount of load that is applied to the first base assembly 74 of the reciprocating ball sports trainer 10. The reciprocating load cell 34 determines the position of the ball 12 with respect to vertical by determining the amount of pressure that is applied either in a forward or reverse direction from the center portion of the ball 12 based upon the torque that is sensed by the load cell 34. When the ball 12 is in the zero position the springs 18, are perfectly aligned straight up and down from the ball mount 14 to the base assembly 74. When the ball 12 is struck, the ball 12, the ball mount 14 and the springs 18, 20 will move away from the point of impact in a positive direction 78 as shown in FIG. 8. As the ball 12 moves further from the zero position to the furthest point away (direction 76) from the center of the arc as shown in FIG. 8, the amount of torque applied to the reciprocating load cell 34 would increase. As this distance increases in the positive direction 78, the pressure on the first base assembly 74 as well as the load cell 34 is also increased. The reciprocating load cell 34 would measure the torque and would provide a reading to the microprocessor to determine approximately how far the ball 12 has traveled from the zero point. This measurement would allow for the determination of the approximate amount of energy that has been applied to the ball 12 to determine how far and how fast the ball 12 would have traveled from the point of impact, if the ball 12 were not attached to the reciprocating ball sports trainer 10.

As the ball 12 starts to come back towards the center or zero point, the amount of torque applied to the reciprocating load cell 34 would be decreased which can also be detected. Once the ball 12 reaches the top dead center or zero point and passes into the negative portion of the arc 76, this motion can also be detected by the reciprocating load cell 34 to determine how long it took for the ball 12 to cycle, as well as to what speed the ball 12 was traveling as it passed over the zero point. Once the ball 12 has reached its maximum travel distance across the arc and into the negative territory 76, the reciprocating load cell 34 would be able to determine how far past the center point into the negative portion of the arc the ball 12 has traveled. As the ball 12 begins to travel back towards the zero point once again, the reciprocating load cell 34 will detect this movement as well.

Once the ball 12 reaches the zero point for the second time, it will then travel into the positive portion 78 of the arc and begin to return toward the zero point for the third time. When the ball 12 reaches the top dead center point or zero point for the third time, this is the precise moment of the desired impact by the user. By calculating whether or not there was a positive or negative force, or no force at all upon the ball 12 at the time of impact, the system can determine whether or not the ball 12 was struck early, late or precisely at the optimum point of contact, which is the zero point. By monitoring each individual impact as well as the oscillation of the ball 12 and the ball mount 14, the present invention itself can determine whether or not the user is contacting the ball 12 early, late or exactly as desired.

When the ball 12 is struck the first time, it would move to the maximum forward position in the arc. As it returns towards the top dead center for the first time, the user does not have enough time to get the racket in place again to hit it before it reaches to top dead center for the first time. As it passes top dead center for the first time, it is moving toward the maximum negative point in the arc. Once it reaches that point, the ball 12 then starts to travel towards the positive side of the arc. Once it reaches the top dead center for the second time it is traveling in the same direction as the user would be swinging. However, the user would not have enough time to swing at the ball 12 a second time. As the ball 12 reaches the maximum forward point of the arc for the second time, and the ball 12 has now passed the top dead center twice, the user can then begin their swing. The goal is to have the user's racket hit the ball 12 at the exact same time that the ball 12 reaches the top dead center for the third time which is when the ball 12 is traveling in the opposite direction as the racket, and a solid hit can be applied to the ball 12.

If no lateral roll is sensed by the reciprocating ball sports trainer 10, this would mean that the user has struck the ball 12 so that it would travel without any angle with respect to the user. However, during a tennis match, there are many instances in which the player would wish to strike the ball 12 so that it would angularly move left or right with respect to the player.

The lateral load cell 32 is used to determine the amount of lateral roll or angulation from vertical, if any, has been produced when the user impacts, as well as the side spin sensed in conjunction with the ball motor/generator 42 the ball 12. This is done by calculating the amount of torque as applied to the ball 12 in a left or right direction, as opposed to the normal arc of travel by the head as shown in FIG. 8. As shown in FIG. 4, the bolts 50 attach the back plate 49 to the ball mount 14 in a manner in which the ball 12 is not angled with respect to the back plate 49. However, additional holes are provided in the rear of the ball mount 14 to allow the ball mount 14 to be adjusted at a particular angle, such as, but not limited to, 45 degrees to the left or to the right. This is accomplished by attaching the bolts 50 to the back plate 49 using holes provided in the back plate 49 to the left or right of center of the back plate 49. When the ball mount 14 and thus the ball 12 is adjusted either to the left or to the right, and the user attempts to put side spin, back spin or top spin on the ball 12, the lateral load cell 32 would be able to detect the amount of side torque or twisting of the ball 12 in the left or right direction. By measuring and calculating the amount of force that is applied, the present invention will be able to determine whether the user is hitting the ball 12 correctly, as well as how much lateral movement from the normal arc shown in FIG. 8, that particular swing has provided. In addition, each impact can be registered and recorded by remote electronic devices or later reviewed by the user or an instructor. In addition, the function buttons 58 shown in FIG. 7 would allow the user to change the amount and type of information which is measured and recorded. In addition, some of this information would be directly provided to the user by the digital display 60.

In addition to sensing when an individual has properly struck the ball 12 as well as to determine various other parameters of the ball striking ability of the individual, the present invention assists the individual hitting the ball 12 at the proper location, i.e., the sensor zero point. In FIG. 6, the base assembly 74 is provided with a first illumination device including a light emitting diode provided directly under the housing 24. The illumination produced by the light emitting diode 62 being directed upward through the housing 24 and the hollow spring 18 to a timing light lens 52 attached to the top of the spring 20. The light emitting diode 62 would shine up through the spring and would impact the bottom of the timing light lens 52 only when the spring 20 is perfectly vertical with respect to the base assembly 74. When the ball 12 is struck by the individual, springs 18, 20 move in positive and negative directions away from the zero point. At this point since the spring 20 is not perfectly vertical above the base assembly 74, the light emitted by the light emitting diode 62 is blocked by the bending of the spring 18 and thus the illumination of the light emitting diode 62 no longer strikes the timing light lens 52 and thus is not reflected back down the tube assembly to be detected by the photo electric detector 66. As the ball 12 travels back to the zero position and comes into perfect alignment with the light emitting diode 62 in the base assembly 74, the path of the light produced by the light emitting diode 62 is no longer blocked by the spring 20 and the timing light lens 52 becomes illuminated again by direct line of sight by the emitting diode 62 located within the base assembly 74. The light hitting the timing light lens 52 would indicate to the user the proper time to strike the ball 12 which is when the ball passes over the zero point of the arc.

A second illumination device including a light emitting diode 64 is provided in the bottom of the base assembly 74 and is aligned with the housing 22 and the spring 18. The top of the spring 18 is provided with a timing light reflector 54. Similar to the light emitting diode 62, light emitting diode 64 produces a beam of light directed from the base assembly 74 up through the housing 22 and the spring 18 which strikes the timing reflector 54 only when the spring 18 is vertical with respect to the first base 74. Therefore, the light produced by the light emitting diode 64 would only strike and illuminate the timing light lens 52 when the spring 18 is in the zero position. The first base assembly 74 is provided with an illumination sensing device including a photo electric detector 66 provided in a cylinder 65 in proximity with the light emitting diode 64. The purpose of the cylinder 65 is to prevent cross-contamination of the light between the light emitting diode 64 and the photo detector 66. The main purpose of this timing light is to determine if the user has struck the ball 12 at the proper time when the ball 12 passes near the zero point within the arc. It is noted that both the timing light lens 52 and the timing light reflector 54 would illuminate the top of the springs 18, 20 at the same time and the tops of the springs 18, 20 would become dark at the same time.

To determine whether the ball 12 has been properly struck on its return arc toward the zero point prior to impact, the microprocessor of the present invention is looking for signals from the lateral load cell 32, the reciprocating load cell 34, as well as the zero point detector associated with spring 18. If the present invention detects an impact of the ball 12 without detecting the pulse from the photo cell 66, the impact was not correct and would not be considered a good hit. If the system of the present invention detects the pulse received from the photo cell 66 and no impact is detected for some period of time before and after this pulse is detected then it would be determined that this hit was not correct. The proper correlation between the impact of the ball 12 and the detection by the photo cell 66 would also indicate whether the hit was late or early. The amount of impact as well as the amount of time passing between the impact sensed and the zero point is detected, can be programmed or changed within the unit to determine a window of what would be considered a good or bad hit. The present invention would be able to determine whether an impact at the zero point or any degree positive or negative of that zero point can be determined as to what would be considered as a good hit.

As shown, for example, in FIGS. 1 and 2, a roller or wheel 38 is located at the point the longitudinal members of the leg base 26 converge together. The purpose of the wheels or rollers 38 is to allow the user to move the device around the training area. Additionally, although a single roller wheel 38 is shown in FIGS. 1 and 2, the unit can be provided with additional rollers to best achieve the amount of movement and direction of movement required by the user. Each time the ball 12 is struck, the impact would carry through the base unit and propel the unit forward based upon the amount of energy that is applied to the ball 12 by the impact. The roller or rollers on the base of the unit have a resistance capability that can be adjusted to allow for the amount of roll desired by the user. This resistance is created by loosening or tightening the butterfly nut 68. In addition to the amount of roll, the direction of each of the rolls so as to allow the device to roll in a particular direction each time the unit is impacted by the user. This will make it necessary for the user to reposition himself or herself next to the device each time the user wishes to impact the device or swing at the device. The rollers can be used by themselves or in combination with a pad or skid 56 as shown in FIG. 5. The use of the pad 56 would be used to prevent the unit from moving after each impact or moving very little in combination with a roller or the pad 56. The pad 56 can be placed on the bottom of the unit to allow it to slide on different types of surfaces such as tennis courts, pavement, wooden floors, carpeting or any other type of flooring or ground material. The device shown in FIG. 5 utilizes elongated springs 31, 33 extending from between the ball mount 14 and the back plate 49 and the base 74 instead of the springs 18, 20 and the housings 22, 24 shown in FIG. 3. Additionally, as shown in FIG. 9, skid pads 80, 82 can be provided at the end of each skid 26 which would also affect the manner in which the training device would move when the ball 12 is struck.

As previously explained, FIGS. 6 and 7 show the use of the first base assembly 74 providing a digital display 60 as well as a plurality of function buttons 58. This first base assembly 74 is attached to the longitudinal base legs 26 at points 90, 92, the longitudinal base legs 26 forming a second base assembly. The microprocessor for controlling operation of the present invention is also housed in the base assembly 74 as well as being powered by one or more batteries or similar devices stored in power pack 88 shown in FIG. 9. The present invention has a variety of different capabilities and functions and can provide a wide range of information not only to the user, but to a coach or instructor as well as uploading information to a website via the Internet. The present invention can be provided with a I-0 port that is capable of being interfaced with a wide variety of different electronic devices or components, for example, the I-0 port can be plugged into a home computer or a device such as a Wii such that remote information and remote players can be interfaced to the unit such that a semi-reality practice match with professionals or other players in other locations can be conducted utilizing the microprocessors. The present invention can also be interfaced with a home game station so that users can practice against computer-generated professionals to help hone their skills. As previously indicated, the present invention can count the number of good hits, bad hits, total number of hits, as well as a percentage of good or bad hits. The present invention can run software programs and allow the unit to provide lessons and determine if the user has reached a skill level that can be programmed by the user or instructor.

As illustrated in FIG. 4, the present invention is provided with a ball spin retarder 40. The spin retarder is used to decrease the amount of rotation of the ball 12 once impacted by the user. The spin retarder 40 is composed of two opposed discs provided between the end cap 16 and the ball 12, each disc provided on either side of the ball 12. These discs would apply friction to the rotation of the ball 12. As the amount of friction is increased by adjusting the pressure on the two discs, the amount of rotation of the ball 12 is retarded. The purpose of the ball spinner retarder is to allow the user to increase the amount of top spin or back spin applied to the ball 12 with each hit. If little or no friction is applied to the ball 12, can spin freely makes it very difficult to determine how much top spin or back spin was applied to the ball 12 each time it was hit. As the amount of resistance is increased, the amount of rotation decreases and allows for the user to determine whether they are applying a substantial or significant amount of top spin or back spin to the ball 12 with each hit of the ball 12.

While the preferred embodiments have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, is intended to cover all modifications and alternate constructions falling within the spirit and scope of the invention.
